And China has a serious shortage of water resources, and face serious water pollution and waste. What has the most toxicity is the chlorophenol, and these chemical have high chemical and thermal stability. They have a strong smell and harm to human health though in the concentration in ppb. The physical, chemical and biology methods are applied to remove the p-chlorophenol are introduced, and the main research direction in removing p-chlorophenol in the future and the problems to be solved are proposed. Keywords: p-chlorophenol ；extraction ；physical absorb ；removal ；biological membrane ；advanced oxidation processes 氯酚(chlorophenol)类物质毒性大，具有致癌、致畸、致突变“三 景。目前萃取酚类物质的都要用到有机溶剂，而有机溶剂存在与水有 致”效应和遗传毒性，并且具有很好的化学稳定性和热稳定性，不易 一定的互溶性、溶剂易挥发、毒性大等缺点，离子液体的特性可以弥 被生物降解或分解。其中氯酚类物质
